Maintain Indoor Humidity Levels

Since moisture is the root cause behind mold production, pay special attention to maintaining the humidity levels inside your home. It is recommended to keep the humidity level below 50% to prevent the growth of mold. You can use a dehumidifier to bring the humidity levels down.

Head to this article and take a look at the ideal indoor humidity chart.

Identifying The Presence Of Mold In Air Conditioner Ducts

You will probably smell a problem with mold before you see it. Mold growth brings a musty odor that some compare to the smell of a wet dog. If there is growth in the ductwork, you may be able to smell the stink in one room or several adjoining rooms. As the colony starts to expand, you may see evidence of mold through black, green, or brown spots creeping out of your air vents in the room where the ductwork attaches. You wont see the individual mold spores unless you have special equipment, and it can take a while before you see the signs. However, the smell often starts long before you see the damage.

How To Check For Mold In Air Ducts

Mold spores thrive in an environment that is warm and moist, such as an air duct. Thus, mold may develop in your air ducts if you have an excessively wet atmosphere with no ventilation or any space that traps moisture in your walls and causes condensation.

Mold testing can help determine if you have mold in air ducts. Mold is often confused with dirt or dust, and you could waste your time and money in the removal process. To confirm that the substance in your HVAC vents is mold, contact a certified mold inspector. They offer laboratory analysis of samples taken from your air ducts.

Besides a mold test, you can also use your nose as the fungus also gives off a distinct musty odor. When your heating or air conditioning is on, you may notice the smell. It will usually be strongest near the mold development vent. As a result, the scent may not be noticeable throughout the entire house but can still be detected in one particular room. On the other hand, the stench might very well continue to linger in adjacent areas and elsewhere throughout the structure.

Mold in air ducts that goes unaddressed for an extended period will absolutely spread throughout the rest of the HVAC systems. Eventually, you may detect the musty odor in every nook and cranny of your house.

How To Treat Black Mold In Your Air Ducts

Does AC Duct Cleaning Remove Mold?

If you suspect that you have a black mold infestation in your home, you need to call a mold remediation professional to inspect your home. The professional will take the steps to test for mold throughout your home. The inspection will verify if your home does have black mold, but if your home does not have black mold, it is also good to do because you can check to see if the mold concentration in your home is too high.

If the professional has verified the presence of black mold in your home, then they will tell you the steps to remove it. For the most thorough cleaning, the professional will have to remove the right components from the air ducts to ensure complete cleaning. The reason is to be sure that the black mold has not touched any other part of your air duct and remove the risk of cross contaminating other parts of your home.

Black mold needs to be cleaned thoroughly by a trained remediation professional because most conventional cleaning agents will not work. Remediation professionals are trained to use the most high-powered cleaning vacuums and motorized brushes to remove black mold from your home.

For example, COIT has the largest and most powerful cleaning equipment on the market we use high-efficiency particulate air vacuums and eco-friendly products to remove mold from your air ducts. Also, COIT finishes the job using air scrubbers to ensure and sustain the availability of high air quality.

Before You Start

Other Common Areas In The Home Where Mold Accumulates

Mold can grow under the fridge by the motor area, beneath the kitchen and bathroom sinks, and on the bathroom ceiling and walls. This is especially true when there is no window in the bathroom and the only ventilation is a vent fan. Its important to make sure that the bathroom vent fans are working and exhaust the unwanted moisture from a steaming shower. Proper function of the fan should be a clear vent line and exhaust to outside of the home. Often contractors will just lead the vent to exhaust into the attic and can cause an unwanted moisture build up there which can lead to a bigger mold issue.

Just because the vents are moldy, theres no need to replace them. As long as structural integrity remains, simple cleaning is enough. If you have a central AC system and the vents are moldy, take a look at the ductwork. Finding mold here a well is not uncommon.

If mold exists within your ductwork, theres no need to worry about replacing that either.

Preventing Mold Growth In Ductwork

How To Clean Mold From HVAC Vents

Now that youve cleaned off the active growth, you need to take action in preventing new colonies of mold. After cleaning, you can use an EPA registered disinfectant fogger to kill spores that may have escaped. You can also apply a mildew inhibitor to your entire HVAC system. Be sure to select a product that is specifically formatted for heating and cooling units and is registered with the EPA. This will limit the risk of applying an ineffective and toxic chemical solution to your unit and the air inside your home. If you dont take steps to prevent growth, you can have another mold problem within just a few weeks in the same area.

Treatment For Mold On Vents & Registers

Not always does mold on the outside of the vents mean that there is mold within the air ducts. Often the contamination is limited to the surface area of the vent which can be treated with a non toxic fungicide spray. Homeowners might think to make their own mold killing solution out of bleach or ammonia but most health experts do not recommend this due to the toxic aerosols that can be breathed in. Ridding the vents of mold can be accomplished by purchasing a non toxic fungicide spray approved by the Environmental Protection Agency or better known as the EPA. If your vent is so constricted that the spray is not doing a good enough job, you may just want to replace it.

Sometimes when the vent is removed you will have a pretty clean air duct. So whats happening is that the moisture is getting trapped in between the supply vent and the ceiling thats allowing the mold to breed. The good news is that the mold issue is not from your duct work but simply limited to the area around the vent. For this you will want to remove the vent, clean it well, and reposition it so that it fits snug into the duct. Other times the vent will be pointing directly onto the ceiling that allows for condensation to accumulate on a specific area on a constant basis that will breed mold. First make sure the mold is removed from the ceiling and then redirect the direction to which the slats are pointing. You want them pointing towards the living space, not the ceiling.

How To Get Rid Of Mold In Your Hvac System

Despite regularly inspecting your system, you are still getting complaints about the smell , here are some tips you can share with your HVAC contractor for cleaning it up:

  • Turn off your HVAC system.
  • Everyone involved in this cleaning should wear at least an N-95 respirator
  • Replace anything porous, such as filters or insulation, that has become wet. Double-bag the waste using 6-mil or thicker plastic bags.
  • Use wet vacuums to clean out any standing water. If vacuuming dry coils, use a HEPA vacuum.
  • Use an EPA-registered disinfectant labeled for HVAC use to clean non-porous surfaces of mold, mildew, and other dirt. BIOSPRAY-TOWER ready-to-use disinfectant and mold cleaner will kill and remove mold, mildew, and odor-causing bacteria.
  • Clean the HVAC evaporator coils using a mechanical coil cleaning system to remove any solid debris.
  • As an added measure, isolate each section of ductwork you clean with bladders so the spores you stir up during cleaning dont spread to other parts of the system or the building. Fog the area with an EPA-registered disinfectant.
  • Apply a mold and mildew inhibitor to all components of the HVAC systems. Again, this must be EPA registered and specifically labeled for use in HVAC systems to limit risks associated with using the wrong chemicals and cleaners in HVAC systems. BBJ Mold Control is EPA registered for use in HVAC systems to control mold growth for up to 2 years.
  • As a final step, HEPA vacuum anything that you cleaned up.
